VACUM OIL IBUB'NE'IR.r

Application filed. October 24, 1924.

To all 10720121, it may concern.'

Be it known that I, VILLIAM R. GIBSON, a citizen of the United Stat-es,residing at Mansfield, in the parish of De Soto and State of Louisiana,have invented certain new and useful Improvements in Vacuum Oil Burners,of which the following is a specification.

This invention relates to improvements in oil burners, and has for its'principal object to provide. a means Vwhereby the atomizi-ng fluidprovides a means for causing the flow of oil through an oil pipe.

A further object of the invention is to provide a vacuum oil burner ofthe above mentioned character, wherein the flow of oil to the oil pipeis dependent upon'the pressure of the atomizing fluid.

A still further object is to provide a vacuum oil burner of the abovementioned character wherein the oil feeding pipe is disposed within theatomizing fluid circulating pipe, whereby the oil feeding pipe will beheated by the atomizingV fluid passing around the oil feeding pipe.

A still further object of the invention is to provide a vacuum oilburner of the above mentioned character, which is simple inclonstruction, inexpensive, strong and durable, and further well adaptedfor the purposes for which it is designated. L

Other objects and advantages of this invention will become apparentduring the course of the following description.

In the accompanying drawing, forming a part of this specification, andin which like numerals designate like parts throughout the saine:

The figure represents a view partly in section, and partly in sideelevation, of the vacuum oil burner embodying my invention.

In the drawing, wherein' for the purpose of illustration is shown thepreferred embodiment of my invention, the numeral 1 designates anelongated pipe, which is of a relatively large diameter. The upper andlower ends thereof are externally threaded. A. head 2 is fitted on theupper end of the pipe 1 as illustrated at 3. The lateral tubularextension 4 is formed on the head 2, and provides an inlet for theatomizing fluid, which may be supplied to the head and pipe 1, byattaching a supply pipe to the outer end of the tubular extension 4. Asimilar head 5 is threaded on the lower end of the pipe 1, asillustrated at 6, and the head 5 is sion 7.

Serial No. 745,648.

also provided with a tubular lateral eXten- The tubular extension 7forms an outlet for the atomizing fluid, which passes through the pipe 1and the head 5, in the manner hereinafter to be more fullyv described.The outer end of the tubular eX- tension 7 is disposed downwardly, asillustrated at 8, and is internally threaded, for receiving thedischarge pipe 9.V l

Extending centrally through the pipe 1, and the heads 2 and 5respectively, is the relatively small oil feed pipe 10. An elbow 11 isthreaded on the upper end of the oil feeding pipe 10, and rests on theannular shoulder or collar 12, formed on the upper head 2, and affordsthe connection with the oil supply pipe 13. A similar nipple 14 isthreaded on the lower end of the oil feeding pipe 10, and is disposedadjacent the annular shoulder or collar 15 formed on the bottom of thehead 5 A discharge nozzle 16 has its inner end threaded into the. nipple14, for communication with the oil feed Vpipe 10, and the outer end ofthe discharge nozzle 16, which is reduced, as illustrated at 17 isdisposed directly below the lower end of the discharge pipe 9, and is incommunication therewith for the purposes to be presently described.

The atomizing fluid, used in conjunction with my improved oil burner maybe either steam or air. The atomizing fluid will enter the head 2,through the inlet 4, and will circulate down through the pipe 1, aroundthe oil feeding pipe 10, and will be discharged outwardly from the head5, through the outlet 7 and the discharge pipe 9. The atomizing iiuid,upon being discharged from the pipe 9 will cause a vacuum or siphonicaction, in the oil feeding pipe 10, whereby the Y oil will be deliveredto the pipe 10, and fed downwardly therethrough, and discharged throughthe nozzle 16, and upon leaving the reduced outer end 17 of the nozzle,the oil and atomizing fluid will be ignited and will provide a flame atthe end of the discharge nozzle.

If the pressure of the atomizing fluid is increased, the heat will beincreased, and the fiance will not go out, when the pressure of theatomizing fluid is increased. When the steam is used as an atomizingfluid, the same, upon passing downwardly through the pipe 1 will, ofcourse, come in contact with the oil feeding pipe 10, and therebysup-erheat the oil as the same is fed through the pipe,

thereby further increasing the eilieiene;T of my iinproi/ed vacuum oilburner. It is also to be understood that the nozzle 16- inay` be readilydisengaged .from the elbow lll onY the lower end of the oil feed pipe10, in order to permit the attachment of any other suit-able nozzle.

Vhile I have shown the preferred embodiinent of my invention, it is tobe understood that variouschangesl in the size, shape7 and arrangementot' parts ina-y he resorted to, without C'l-eparting from the spirit ofthe 1nrention and the scope of the appended el aiin.

Having thus described iny invention, what is claimed is:

A ifaeuun'i oil burner eoinprisng a cylindrical easing, a head on theupper end thereof,' a tubular lateral extension associated with the headcomprising an atoinizing 'luid inlet, an additional head on the lowerend of the casing, a tubular extension associated with the lastmentioned head and providing an outlet-:for the atomizing Huid, adischarge pipe in the outer end of the tubular extension providing anoutlet, an oil pipe extending centrally through the easing and throughsaid head, asupplT pipe associated with the upper end thereof, and anoil discharge nozzle on the lower end of the oil pipe, the outer end ofthe nozzle heing disposed in Communication with the outer end of thedischarge pipe.

In testimony whereof I affix my signature.

VV'ILLIAM R. GIBSON.
